  • Patent number: 11183401
    Abstract: An industrial-scale system and method for handling precisely aligned and centered semiconductor substrate (e.g., wafer) pairs for substrate-to-substrate (e.g., wafer-to-wafer) aligning and bonding applications is provided. Some embodiments include an aligned substrate transport device having a frame member and a spacer assembly. The centered semiconductor substrate pairs may be positioned within a processing system using the aligned substrate transport device, optionally under robotic control. The centered semiconductor substrate pairs may be bonded together without the presence of the aligned substrate transport device in the bonding device. The bonding device may include a second spacer assembly which operates in concert with that of the aligned substrate transport device to perform a spacer hand-off between the substrates. A pin apparatus may be used to stake the substrates during the hand-off.

  • Patent number: 9859141
    Abstract: A device for locating and engaging a notch on the perimeter of a circular wafer includes a notch locating component and a first plate. The notch locating component is configured to move linearly along a first axis and includes a front elongated component extending along a second axis perpendicular to the first axis and having a front surface, a back surface opposite to the front surface and a first protrusion extending from the front surface of the elongated component. The first protrusion has a shape complementing the shape of a notch formed on the perimeter of a circular wafer. As the notch locating component is driven toward the perimeter of the circular wafer along the first axis, a distance between the back surface of the elongated component and a front surface of the first plate is measured and the value of the measured distance is used to determine engagement of the first protrusion with the notch.
